Our 11 month old DS intentionally hits people in the face and chest, as well as scratching and biting (although the latter is largely due to teething). It's painful and also embarrassing if he lashes out at someone who just wants to say hello...
What can we do to discourage? Say no firmly then put him down or walk away momentarily? Or would this lead to worse behaviour? Don't want to make it a game but also don't want to make him insecure.
Any advice?
